Mio Board - Stratasys FORTUS 360mc Service Manual

MIO Board

Purpose
Receives and distributes motion, temperature, and filament information/messages. The MIO
board also distributes 24/48V DC to the system.
Components, Circuits, and Operation
1.
AC board/MIO interface provides:
• Pass though of HVDC 1 and 2 for head heaters.
• Safety circuit connections.
• Communication connections.
• Oven heat control signal.
2.
24/48V DC interface to system:
• 48V DC supply for 3 servomotors.
• 24V DC supply for head board, drive blocks, oven thermocouple, etc. -
• Creates -24V DC and 5V DC.
3.
Motion Control interface:
• Uses two PMD boards located in the computer to control motion that are
• All axis motion and extrusion is controlled by the motion control board(s).
4.
XYZ axis servo amplifiers:
• There are 3 self-contained servo amplifiers mounted on the MIO board.
• The PMD board(s) in the computer sends reference signals to each
• The amplifier applies power to the motor and monitors the motor encoder
• The amplifier makes speed and current changes as required to keep each
• The amplifiers are also equipped with an Enable input - used to remove
5.
Head filament drive motor servo amplifiers
• Part of the MIO board circuitry - P1 (Model), P2 (Support).
• The motion control board(s) sends signals to each amplifier.
• The amplifier applies power to the motor.
